This Review outlines the ability of DNA to direct the organization of particle-based building blocks into crystalline architectures. These advancements permit programmable control of each structural element of colloidal crystalline materials and enable the design of functional and responsive behaviours.]]>Christine R.

The shape of water

Laser pulses can trigger fast changes in magnetic state, facilitating new magnetic data storage and memory devices. This Review outlines the mechanisms of all-optical switching and the materials suitable for the optical control of magnetism and tests these mechanisms and materials in terms of speed, accompanying dissipations and scalability. Finally, the large-scale integration of devices in memory applications with low-energy dissipations is discussed.]]>Alexey V.

Metal halide perovskite nanostructures for optoelectronic applications and the study of physical properties

Metal halide perovskite nanostructures for optoelectronic applications and the study of physical properties, Published online: 05 February 2019; doi:10.1038/s41578-019-0080-9

Metal halide perovskite nanostructures are promising materials for optoelectronic applications. In this Review, we discuss the synthesis and properties of 1D and 2D single-crystal perovskite nanostructures, examine potential optoelectronic applications and highlight recent studies in which these nanostructures have been used to study the fundamental properties of perovskites.]]>Yongping FuHaiming ZhuJie ChenMatthew P.

Engineering mucus to study and influence the microbiome

Mucus is a 3D hydrogel composed of mucins that houses the human microbiome. Mucus guides microbial cell fate and is involved in the suppression of pathogenic bacteria. In this Review, the authors discuss the design of synthetic mucins for the investigation of mucus–microbiome interactions and for applications in 3D in vitro cell culture.]]>Caroline WerlangGerardo Cárcarmo-OyarceKatharina Ribbeckdoi:10.1038/s41578-018-0079-7Engineering mucus to study and influence the microbiome, Published online: 2019-01-24; | doi:10.1038/s41578-018-0079-72019-01-24Engineering mucus to study and influence the microbiome10.1038/s41578-018-0079-7https://www.nature.com/articles/s41578-018-0079-7https://www.nature.com/articles/s41578-018-0079-7
